I appealed during PAE so i suppose it should be similar.
Appeal online from the school's website (if they offer that
feature) / Go to the school's general office to ask for a appeal
form. Fill it up and give it back to them.
You should be informed within two days or so.(supposedly it is
successfully)
Go back to the school to get a transfer letter.
Now you will have to take the transfer letter to the new school
that you are going to transfer to. Get the letter signed by the VP
or maybe the Principal. They may ask you a few questions like why
you want to transfer?...
Now go back to the School you posted to , to submit the
letter(signed). Finished.
Things you need:
A photocopy of your result slip
Photocopy of CCA / CIP records
Be prepared to answer questions , like why do you want to appeal
to that school? *Important* Or maybe an interview depending which
school you appealing to.
